The Abbey of St Vaast (French: Abbaye de Saint-Vaast) was a Benedictine monastery situated in Arras, département of Pas-de-Calais, France.

Vedast's relics were transferred to the new abbey, which was completed by Auburt's successor and generously endowed by King Theuderic III, who together with his wife was afterwards buried there.

[2] By 867, a vicus monasterii had grown up around the monastery, inhabited by people employed in various crafts such as bakers, brewers, and smiths who provided services to the abbey.

Between 1433 and 1435, Abbot Jean de Clercq commissioned Jacques Daret to paint an altarpiece for the abbey church.

The four panels depict the Visitation, the Nativity, the Adoration of the Magi, and the Presentation in the Temple, all now dispersed among various museums.
